Type species: Apophysius bakeri Cushman by original description.

Diagnosis. Apophysius is characterized by numerous apomorphies. Head and mesosoma densely covered with long blond setae; apical margin of clypeus broadly convex, with two small projections at the center; upper mandibular tooth larger and much longer than lower tooth; occipital carina complete; mesoscutum with notauli indistinct; subtegular ridge sharp, laterally expanded in dorsal view; posterior edge of mesoscutum with suture before scutoscutellar groove; propodeum with four tubercles (apophyses) at intersections of lateral longitudinal carinae with anterior and posterior transverse carinae; tarsal claws conspicuously pectinate proximally; fore wing with vein 3 rs-m present, almost parallel to 2 rs-m, areolet large, pentagonal, wider than high, 2 m-cu weakly angulate with one wide bulla; hind wing nervellus reclivous; first tergite long and slender, completely fused with sternite, without carinae, spiracle at middle.

Townes (1970) places Apophysius in his subtribe Bathytrichina , together with Chrysocryptus Cameron , a genus recently recorded from Vietnam ( Pham et al. 2019). Species of both genera have dense, long blond setae covering the head and mesosoma and slender first metasomal segments lacking carinae. Apophysius can be distinguished from Chrysocryptus by the indistinct notauli on the mesoscutum, the presence of two instead of three projections on the clypeus, and the two sets of apophyses on the propodeum.
